We have previously shown that FAPP2 is involved in apical transport from the Golgi complex in epithelial MDCK cells. In this paper we assign an unknown activity for the protein as well as providing structural insight into protein assembly and a low-resolution envelope structure. By applying analytical ultracentrifugation and small-angle x-ray scattering, we show that FAPP2 is a dimeric protein in solution, having a curved shape 30 nm in length. The purified FAPP2 protein has the capability to form tubules from membrane sheets in vitro. This activity is dependent on the phosphoinositide-binding activity of the PH domain of FAPP2. These data suggest that FAPP2 functions directly in the formation of apical carriers in the trans-Golgi network. 000094235 536__ $$0G:(DE-H253)POF1-No-Ref-20130405$$aFS Beamline without reference (POF1-550)$$cPOF1-550$$fPOF I$$x0 000094235 588__ $$aDataset connected to Pubmed 000094235 650_7 $$00$$2NLM Chemicals$$aAdaptor Proteins, Signal Transducing 000094235 650_7 $$00$$2NLM Chemicals$$aLipid Bilayers 000094235 650_7 $$00$$2NLM Chemicals$$aPLEKHA8 protein, human 000094235 650_7 $$00$$2NLM Chemicals$$aPhosphatidylinositols 000094235 650_7 $$00$$2NLM Chemicals$$aSolutions 000094235 650_2 $$2MeSH$$aAdaptor Proteins, Signal Transducing: chemistry 000094235 650_2 $$2MeSH$$aAdaptor Proteins, Signal Transducing: metabolism 000094235 650_2 $$2MeSH$$aAdaptor Proteins, Signal Transducing: physiology 000094235 650_2 $$2MeSH$$aAnimals 000094235 650_2 $$2MeSH$$aCell Line 000094235 650_2 $$2MeSH$$aDogs 000094235 650_2 $$2MeSH$$aLipid Bilayers: metabolism 000094235 650_2 $$2MeSH$$aPhosphatidylinositols: metabolism 000094235 650_2 $$2MeSH$$aProtein Binding 000094235 650_2 $$2MeSH$$aProtein Conformation 000094235 650_2 $$2MeSH$$aProtein Multimerization 000094235 650_2 $$2MeSH$$aSolutions 000094235 650_2 $$2MeSH$$atrans-Golgi Network 000094235 693__ $$0EXP:(DE-H253)Unknown-BL-20150101$$6EXP:(DE-H253)Unknown-BL-20150101$$fUnknown DESY Beamline$$x0 000094235 7001_ $$aCoskun, Ü. 000094235 7001_ $$aRössle, M. 000094235 7001_ $$aBuschhorn, S.
